but pyongyang shouldn't misread china, china won't put its relations with pyongyang above other strategic interests. that's fairly harshly worded. >> it is. a good rhetorical shift. we need china to go for tough sanctions and enforce those sanctions. right now, china has been letting the north koreans sell a lot of missile technology to the iranians, crossing over chinese territory. april 15th last year, in the big military parade in pyongyang, six chinese missile launchers sold to pyongyang. we need to have some important conversations with china, we've not been willing to do that in the past. >> you mentioned iran. quickly, let's talk about that. iran getting access to the opportunities that north korea is creating and being successful with. what happens there? >> in 2006/2009, iranians on site in north korea for the two previous nuclear tests. north korea sells everything it develops to the irianians, long-range ballistic missiles, nuclear reactors, processed uranium, you name it. this is a joint nuclear weapons development program in tehran and pyongyang. we need to stop those sales.
